The Javelin charge consists of a cluster of Iridium Fletchets with a Graviton Pulse Detonator. This allows for much higher damage than can be achieved by a standard rail system. However, the inherent entropy of graviton pulses means that it is very hard to maintain accuracy at long range. 75% reduced optimal range. 25% increased tracking speed. Note: This ammunition can only be used by large tech level II Railguns.
